The DJIA is set to follow its global counterparts into the green on hopes for a Greece debt deal

The Dow Jones Industrial Average (DJIA) is on pace to erase all of Friday's triple-digit loss, on hopes that Greece will come to an agreement with its creditors at today's emergency summit. Over the weekend, the fiscally strapped nation sent a new list of proposals to eurozone finance ministers, a move that is being hailed as positive by a number of top officials. Additionally, the European Central Bank (ECB) once again increased the limit on emergency funding for Greek banks -- the third time it's done so in a week. Back on the homefront, existing home sales will be released at 10 a.m. ET.

Traders will be watching a special summit of eurozone finance ministers, who are meeting to discuss Greece's debt situation. On the home front, investors will digest the existing home sales report for May. After the close, fast-food firm Sonic (NASDAQ:SONC) will report earnings.
